withstand safely. CAT IV is the highest category — covering measurements at the origin of the installation, including service entrances, electricity meters, overhead line connections and outdoor conductors. CAT III covers distribution panels, consumer units and fixed equipment. The ProScope's dual CAT IV 600V \/ CAT III 1000V rating means it provides the maximum level of certified protection for professional electricians working across the full range of UK electrical environments — from domestic consumer unit work to commercial and industrial installations.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the ProScope suitable for use on commercial and industrial electrical installations?\u003c\/summary\u003e\n\u003cp\u003eYes — the CAT IV 600V \/ CAT III 1000V rating, True RMS measurement and comprehensive measurement capability make the ProScope appropriate for professional use in residential, commercial and industrial electrical environments.

The blown fuse alert specifically warns when the internal current measurement fuse has failed — preventing inaccurate current readings and alerting the user that the fuse needs replacing before the instrument is used for current measurement again. Both features significantly reduce the risk of measurement errors and instrument damage on site.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the ProScope compare to the other multimeters in the Forjato range?\u003c\/summary\u003e\n\u003cp\u003eThe \u003cstrong\u003eProScope\u003c\/strong\u003e is the only multimeter in the Forjato range with an explicit \u003cstrong\u003eCAT IV 600V \/ CAT III 1000V safety rating\u003c\/strong\u003e — the highest available.
